The sound comes from Bethesda's Fallout role playing series, where quest and mission updates are marked by distinctive interface stings as objectives complete and experience is awarded. The series began in 1997 and its post apocalyptic setting, Pip-Boy menus and retro futuristic sounds became widely recognised in gaming culture. Clips of the completion sting spread through YouTube edits, streams and soundboards, where fans reused it outside the game as a universal signal for finishing something difficult. Its clear meaning keeps it popular for achievement memes.
